Does multiculturalism decrease or increase intolerance?

Do you find that multiculturalism is accepted and embraced and has had a positive impact on the area you live in ... or is there more intolerance as a result of the increase in diversity of your local community?

Increases.
There is very little multiculturalism in my borough as those of different race have integrated into local society.
Multiculturalism results in less integration and less integration can only increase intolerance.

Those of us who both celebrate diversity and welcome multiculturalism in all its myriad aspects tend not to live in areas where multiculturalism is enacted.
( Class formerly known as...)... 'Working-class' white people in Bradford though.
Maybe not so much.
